I have successfully got the information by onClick function. But is there any method i can get the point information on Hovering over the point. Right now onHover as mentioned in docs is not working to get the point. This is my jsFiddle.
In previous versions of Chart.js (for example 2.6) the onHover handler has to be configured as below:
hover: {
onHover: function(evt, item) {
if (item.length) {
console.log("onHover", item, evt.type);
console.log(">data", item[0]._index, data.datasets[0].data[item[0]._index]);
}
}
},
itme[0]._index property points to data of target item
So your fiddle (chart.js 2.6) updated is: https://jsfiddle.net/beaver71/440L5661/
With chart.js 2.7: https://jsfiddle.net/beaver71/ttrak7sj/

How to fix the problem of having the navbar as position: fixed in Sitecore 9.3. I saw some solutions on the blogs, but it only fixes the issue on the Sitecore 8 versions.
Basically when I open the partial design in Sitecore Experience Editor, I have set my navbar as position fixed in theme css file, and it shows the navbar below the scWebEditRibbon. I also saw that scWebEditRibbon is now position fixed, still it does not fix my issue since I also have position fixed on my element.
I fixed the issue by using the script provided Richard Szalay, I just changed the variable as you can see here:
Here is the script:
// Repositions a position-fixed header so that it always appears under the SC experience editor ribbon
define(["sitecore"], function (Sitecore) {
return {
priority: 50,
execute: function (context) {
// TODO: Change this CSS selector to suit your application
var FIXED_NAV_SELECTOR = '#navbar';
// the 'cross piece' is a blank div that is sized to match the iframe content (where the actual ribbon is)
var scWebEditRibbon = window.parent.document.getElementById('scWebEditRibbon');
var nav = window.parent.document.querySelector(FIXED_NAV_SELECTOR);
if (scWebEditRibbon && 'MutationObserver' in window) {
var observer = new MutationObserver(function (mutations) {
nav.style.top = scWebEditRibbon.style.height;
});
observer.observe(scWebEditRibbon, { attributes: true, attributeFilter: ['style'] });
}
}
};
});
I'd like to append a new menu entry right below "Enter Full Screen", but I am failing to find the right CommandGroupPlacement property.
CommandGroup(after: .<what needs to be put here??>) {
//my buttons here
}
Attempting to override "View" results in just another group with the same name (see image).
CommandMenu("View") {
//add button here
}
Shoutout to Majid Jabrayilov for his blogpost on this: https://swiftwithmajid.com/2020/11/24/commands-in-swiftui/
To find a solution to my above issue though I still had to think a bit around the corner–what does work is this:
CommandGroup(before: .toolbar) {
Button("Foo") {
}
}
This works, because the toolbar menu entry is located within "View" (even thought I don't have a toolbar in my app, the placement still works nonetheless...)
You said you were looking for the proper CommandGroupPlacement so for your case (relative to full screen mode), you would technically want CommandGroupPlacement.sidebar. CommandGroupPlacement.toolbar works because toolbar options live in the View menu, though you have none set.
/// Example in a CommandsBuilder
CommandGroup(after: CommandGroupPlacement.sidebar) {
Button("New View Action", action: { print("After sidebar menu options") }).keyboardShortcut("s", modifiers: [.command, .option, .control, .function]
}
This should also come in handy for others. The Apple documentation that corresponds to this: CommandGroupPlacement
I am using bubble charts in angular-charts (its based on charts.js)
Users have to hover on bubbles to know their labels
How can I either show labels or turn on tooltips permanently in bubble chart

You need to specify it within the options of Chartjs, specifically the callback part. I've given an example of what that looks like. Chart JS Documentation
vm.options = {
"callbacks": {
"label": function (tooltipItem, data) {
return data.datasets[tooltipItem.datasetIndex].label;
}
}
I'm having a chart build with ChartJS. I'm including datasets.label in multipleTooltipLabel template and facing an update issue. When changing a datasets.label and running chart.update() the tooltip is not updated. I created a JSFiddle demonstrating the issue.
The code I use to include datasets label in tooltip:
var options = {
multiTooltipTemplate: "<%=datasetLabel%>: <%= value + ' %' %>"
};
Beside that option I followed ChartJS usage example for Line charts.
Change label and update chart:
myNewChart.datasets[0].label = 'updated label';
myNewChart.update();
Label shown in tooltip is not updated...
I had a look in ChartJS source code and figured out that showTooltip function is called with a ChartElements array which was not updated.
Update: I might cached the issue. label of dataset is set on each point element and not updated if it changes. showTooltip used this "cached" dataset label when drawing a tooltip. Perhaps this should not be a question on StackOverflow but a bug report for ChartJS.
I found a solution:
myNewChart.datasets[0].points.forEach(function(point) {
point.datasetLabel = 'updated label';
});
This might also be the way it should be done. Chart.js documentation of update method says you should set myLineChart.datasets[0].points[2].value = 50; to change the value. That's confusing cause on creation dataset expects the values in data property. points is generated by Chart.Line Class on init. Naming may be different for other chart types (eg. it's bars for a bar chart).
I'm not quite sure if myLineChart.datasets[0].label value is used somewhere or if could be unchanged.
I could solve your problem by changing the original data object (data.datasets[0].label='updated label') then running myNewChart.initialize(data).
var option = {
plugins: {
tooltip: {
callbacks: {
label: function (context) {
//console.log(context);
label = 'new string ' + context.label + ', ' + context.dataIndex;
return label;
}
}
}
}
};
myChart.options = option;
ToolTips / Points Events are configurable with chartJS options...

I'm trying to implement a BB10 settings menu, looking like the one in the Calendar app for example. The question here is, which components should I use? Using a ListView with an XML model looks great, but is incompatible with translation. Using a C++ model looks overkill for a simple menu with a couple of entries…
There's probably an established pattern somewhere, but I can't find it.

What you want is the expendable content property of the title bar:
I would create a QML object that you can re-use for each entry with properties for title and image.
So for example, something perhaps like this:
SettingEntry.qml
Container {
property alias title:title.Text
signal click()
TextView {
id: title
text: "[title goes here]"
}
gestureHandlers: [
TapHandler {
onTapped: {
click();
}
}
]
}
Then in your settings page you would use it like a normal object:
Page {
Container {
SettingEntry {
title: "General"
onClick: {
//open general page
}
}
SettingEntry {
title: "Invitation Settings"
}
}
}
The above is obviously very simplified, you would want to include an icon image, add translation code and add visual adjustments like filling the width and padding.
It should however give you a good idea of where to start.
I also included a gesturehandler and signal to show you how to handle events such as a click.
